DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bumper side protector structure for preventing adjacent body panels from being damaged when a bumper side portion that bends laterally from a front portion of the bumper.

[0002]

2. Description of the Related Art As shown in FIG. 5, a bumper side portion 1a of a front bumper 1 that bends laterally from a front portion of the bumper in the vehicle width direction has an upper surface fixed to a fender, and has a lower surface when a collision occurs. The rear edge 1 of the side portion of the arch portion of the fender 2 so as not to be deformed by the rearward movement.
The part adjacent to b is eliminated (A in the figure), or another synthetic resin material 3 is attached to the fender 2 (B in the figure). According to Japanese Utility Model Laid-Open Publication No. Sho 61-37051, similarly, in a state in which the portion adjacent to the rear edge 1b of the side portion is eliminated, the mounting portion to the fender is bumper so that the upper fender is not damaged at the time of collision. A mounting structure that is detachable together with the side portion 1a so as to be movable rearward is also known.

[0003]

However, the latter detachable mounting structure is also based on the premise that adjacent fender portions are eliminated, and does not take into account the design properties around the bumper side portion.

SUMMARY OF THE INVENTION In view of the foregoing, it is an object of the present invention to provide a bumper side protector structure that prevents a bumper side portion from damaging an adjacent fender panel at the time of a bumper collision.

[0005]

In order to achieve this object, according to the present invention, according to the present invention, damage to a fender panel adjacent to a bumper side portion which bends from a front portion of a bumper to a side is prevented in the event of a collision. In the bumper side protector structure, a shoulder portion is formed in the bumper side portion so that the lower portion of the fender penetrates from above, and a shoulder portion along the shoulder portion is formed on a flange portion of the lower edge of the fender along the shoulder portion. Attach a strip-shaped bumper side guide member that extends downward from the position corresponding to the upper end position of the part and extends horizontally to the position corresponding to the end position of the shoulder, and the bumper side guide member is substantially the same as the outer surface of the lower part of the fender Formed in a planar shape,
And a flexible fin that covers the gap to the shoulder,
A guide surface having a substantially triangular cross-section extending obliquely from the base of the fin beyond the tip of the flange of the shoulder is formed.

The gap between the shoulder and the adjacent lower edge of the fender is covered with a fin. When a collision accident occurs in the bumper from the front-back direction and the bumper side moves in the extension direction, the tip of the flange part in the area descending from the upper end of the shoulder of the bumper side collides with the guide surface adjacent in the front-rear direction. Then, the fin is bent along the triangular inclination, and the back surface is slid toward the outside of the passenger compartment. At this time, when the flange portion in the horizontal region of the shoulder portion moves upward, the flange portion slides along the adjacent guide surface in the vertical direction, and is displaced outside the vehicle compartment while moving upward. The guide surface extends beyond the front end of the flange portion, so that the guide surface slides in the vehicle interior direction even when a force in the vehicle interior direction is applied when the bumper side portion moves in the extension direction.

[0007]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A steel front bumper of an automobile according to an embodiment of the present invention will be described with reference to FIGS. The lower part 2a of the fender 2 is lowered from the upper end 51 of the bumper side part 1a into the bumper side part 1a which is bent rearward from the front part of the bumper side part of the front bumper 1 in the horizontal direction so as to bite from above. A shoulder 5 is formed which is bent and cut out so as to reach its end 52.

The edge 2b of the fender lower portion 2a is formed in a corresponding shape with a gap 9 in the shoulder 5, and faces the flange 50 formed by bending the edge of the shoulder 5 toward the vehicle interior. Shaped flange portion 20 bent to the vehicle interior side
Are formed.

The flange portion has a strip-shaped synthetic resin bumper side guide member extending downward from a position corresponding to the upper end 51 of the shoulder portion 5 and extending horizontally in the vehicle front-rear direction to a position corresponding to the terminal end 52. 10 (FIG. 2) is affixed with double-sided tape and riveted. The bumper side guide member is formed integrally with a guide portion 12 surrounded by a soft material skin 14 using a hard material as a core 11 and the same material as the skin 14 in substantially the same surface as the outer surface of the fender lower portion 2a. It is composed of fins 13 colored in the color of the outer panel. When the flange portion 50 of the shoulder portion 5 collides, the outer skin 14 protrudes obliquely from the base of the fin portion 13 toward the vehicle interior so that the distal end 50a slides outward from the vehicle compartment. The guide surface 12a has a triangular cross section and extends beyond the guide surface.

In a normal state, the gap 9 is covered by the fin 13 so as to be substantially flush with the outer surface of the fender lower portion 2a.
If a collision accident occurs on the front bumper 1 from the front,
The front end 50a of the flange portion 50 in a region descending from the upper end 51 of the shoulder portion 5 of the bumper side portion 1a is connected to the fender lower portion 2a.
Guide surface 12a (FIG. 1A) at the corresponding portion of the edge 2b
, And slides rearward along the triangular inclined surface to be displaced outward of the vehicle compartment. At this time, the end 52 of the shoulder 5
When the flange portion 50 in the region extending to the upper side moves upward, the guide surface 12 of the corresponding portion of the edge 2b adjacent to the upper side similarly rises.
a (FIG. 1B), and is displaced outside the vehicle compartment while moving upward. When further moved, as shown in FIG. 4, the back surface of the fin portion 13 continues along the guide surface 12a, and the flange portion 50 moves to the outside of the fender 2. At this time, the tip 5 of the flange 50 is
At 0a, the fender lower part 2a or the coating does not have to be damaged. The guide surface 12a is located at the tip 50a of the flange 50.
And extends into the shoulder portion 5 so as to be surely slid outside the vehicle compartment. When the collision is released, the fin 13 returns to the normal position due to its elasticity.

The present invention can be applied to a rear bumper so as to slide in a vehicle exterior direction in the event of a collision from behind, and the same applies even if the bumper is made of resin.

[0012]

According to the present invention, the lower part of the fender is made to bite into the bumper side from above, so that the bumper extends below the lower part of the fender and the design around the bumper side is enhanced. When the bumper collides, the bumper side slides on the guide surface and is pushed out of the cabin,
Adjacent fenders are prevented from being hit directly. That is, it is possible to increase the degree of freedom in designing the body panel around the bumper side portion while preventing damage to the lower portion of the fender located at the adjacent position. Since the gap between the bumper side portion and the fender is also covered by the fin portion, the appearance is further improved. The fin also has a function of preventing damage to the lower part of the fender or its coating by being turned outward.
